How it Works

The script defines an array called blockedWords containing phrases used for filtering.
The removeDiscoverMore function performs the core removal logic:
- It selects all elements with the data-testid="cellInnerDiv" attribute.
- Iterates through these elements in reverse order for proper removal.
- For each element, it checks the heading text for any blocked word.
- If a blocked word is found, the function removes the current element and all its following siblings with the same test ID.
The removeElements function is a helper function used to remove elements efficiently:
- It finds the index of the element within its parent node.
- It hides all following siblings using display: none instead of complete removal to avoid triggering Twitter's re-rendering.
The script calls removeDiscoverMore initially to remove existing elements.
Finally, a MutationObserver is created to monitor the DOM for changes. Whenever the DOM structure changes (e.g., new elements are added), the removeDiscoverMore function is re-executed to remove any newly added elements containing blocked phrases.
